Alcons has debuted its LR18 pro-ribbon line array. The three-way, “compact-mid-size” format line-source sound system implements Alcons’ pro-ribbon technology for mid and high frequencies and a fast impulse response with up-to-90 percent less distortion. This enables the LR18 to offer a fully intuitive linear response, with very high intelligibility and non-compressed identical tonal balance at any SPL.
The all-natural cylindrical wavefront of the purpose-designed RBN702rs 7″ pro-ribbon transducer and the acoustically and electronically symmetrical component configuration bring a remarkable pattern control in both the vertical as well as the horizontal plane, without any distortion-inducing horn constructions.
The pro-ribbon’s power handling of 1500W and RMS-to-peak ratio of 1:15, caters for what Alcons says is “a superb intelligibility and throw with maximum dynamic headroom reserve.” The MF-section features a high-efficiency 6.5” mid-range transducer with Neodymium motor-structure co-axially mounted behind the RBN702rsr pro-ribbon driver.
The LF section consist of two extended-excursion, reflex-loaded 8” woofers with oversized 3” voice-coil Neodymium motor-structure. Alcons says this 8” surpasses the output of even larger drivers in higher-category line-array systems.
The LR18 is driven by two channels of the Sentinel amplified loudspeaker controller, optimizing the system’s response by LR18-specific drive processing and feedback for each array configuration, including presets for phase-matched low-frequency extensions.
